Ben Affleck Says Playing Batman in The Flash Was 'Fun' After 'Difficult' Justice League Shoot "What's really interesting is how much more I got [Batman] when I went back and did him," he said. "I get this on a whole other level now. I totally respect it. I respect what people are trying to make. I never looked at it like, 'Oh, this is just a silly thing.' It was not a silly thing when I did Batman. But it has become a giant thing, culturally. It's iconic. So I have even more respect for it because, what do I know? This is a big deal in the world to people. You've got to honor that and be respectful of that. Even I go, 'Jesus, this is huge.'" The Flash will also see Ben Affleck reprise his Batman character (he played the role in 2016's Batman v Superman: Dawn of Justice). While Robert Pattinson is the next Hollywood star to take over the role in the upcoming The Batman. The Flash is slated for a June 3, 2022 release.
